IMO only the first 2-3 chapters were engaging. Outside of that pretty underwhelming.

Pretty underwhelming for King's usual standards.

I don't specifically have the criticism for the contents of the book. But writing in this book is horrible. It eventually got slightly better. Overall it was hard to follow and often distracting.

Rating - 3.5
YMMV

Such a fascinating subject. Unfortunately I found author's writing style pretty distracting and superfluous. I had to drop it halfway through.

A nice read for high school or below high school students.
